Application filed Septenzi-er 2 9. 1908. Serial No. 455.385.

To all whom it may eoncern. I

lie it kn wn that l. Jolzx' i). lhnamzx a l citizen of the lnitedStates. ie idingr atl ll rwyn. in the ounty of (ook and State orlllinois. have invented a certain new and useful improvement in Steam,Air. and Water Trap Valves, of \Vltltlt th toilowing is a speeili ation.

Thi invention relates to trap valves more} partienlarlv adapted for usewith steam} heatin g systems J attachment to a rad ator l r heatingeoili t'or automatiealhv diseharging water of eoinlensation. but canalso be med as a trap valve in disehargine liquids and mediums ot'\arion kinds. and thisl without any particular attention from anoperator, when the trap valve is once ad justed for use.

The olrieet of the invention are to con strnet a trap valve consistingof a easing having a ehambei: with :1 Hunt loeatcd in the chamber andadapted to be elevated with j the rise of the water of eondensation orother medium in the chamber. the chamber t having: an inlet passage forthe water all condensation or other medium. and an out i let passage themouth of whieh opens: into; the chamber at a point approximately in:line with the longitudinal renter of thel float when at rest or innormal position, and i the float having an inlet at its upper end i andan outlet at its lower end for escaping t air as the. water ofcondensation, or other medium. rises in the tloat chamber; to eonistruet a trap valre having a lloat controlling the di charge of water ofcondensation, or other medium, the float having, at. the upper'end, afree passage for air, which passage surrounds a guide stem and l openedand ('losed by a valve seat on the stem, as the float is lowered andraised by the water of condensation, or other medium, and the floathaving, at the lower end, a passage for edueting air from the. interiorof the fl at iii the operation of the trap valve; to furnish a freepass-age for indueting, air from a float ehainher into a float at theupper end, said p: ,ge controlled by a valve. and to furnish a )assagefor t' lllt'llllg air from the interior oi the float; and toimprovegenerally the construction and operation of the several elements:entering into the trap valve as a whole.

The invention consists in the features of construction and combinationof parts herel inaiter described and pointed out, in the claims as new,

ln the drawings the ligure is a sectional elevation of the trap titre.of the present invention with the tloat partly in full elevati n and inits normal or seated position.

The trap valve of the present invention t has a shell or easing l il-losing a eh' tnber L. whi h caning is open at the top and t'l rttl atthe bottom. ex ept in having a discharge passage for the water ofcondensation. formed in the chamber 2 of the easing. or lot thedischarge of other liquid or llH-tlillltl from the. chamber. An inletpassage. 3 formed in a neck 4 of the shell or casing opens into thechamber 2 adjacent to the bottom of the chamber; and eonnecb ing withthe neck 4 is a union nipple 5 havin; a passage twhieh opens into thepassage 23; and the union nipple is connected to the ne k hya nipple nutT, as usual.

The open upper end of the shell or easing l is closed by a cap 8,having, a depending rim or flange t) with a n exterior screw thread hwhich the cap is threaded into the end of the shell or casing, and whenin place a tlange to on the eap abuts against the end face of the shellor casing, so as; to make a tight joint between the cap and the shell orIeasing. The cap 8, on its under side, as

shown, is formed with a chamber or cavity 11. to permit of the operationof the lloat. pln; 1; is threaded into the cap 5 at the c nter, and thisplug has a threaded end for entering and securing the plug in position.

The lower end of the shell or casing I hasformed therewith a neck orboss 14, having al threaded hole 15 for the attachment of a dis-- chargeor vacuum pipe, in the use of the. trap valve. The threaded hole 15opens into 1' chamb r H3, and a port- 17, opens into the chamber lti.\\lllt'll port 17, in the construction shown. is formed in a plug 18threaded into a hole l5), formed in the bottom wall of the shell oreasing l, as shown. The plug 1 as shown, has a llange or rim fit) to litclosely against the inner face. of the bottom wall of the sh ll oreasiin l, and the upper face :21 ot the plug 1 in tho eonstruetiongllUWH, is" tapered or inclined so as to prevent a-ipetunulat'ion ofsediment. that would interfere with the operation of the lluat. The plug18 has a central passage or hole 2:! extending to the port 17, andterminating in a seating face 23 around the port; and, leading into thepassage or hole 22, is a cross passage 24 forming, with the passage orhole 22, and port 17, a discharge passage for the water of condensation,or other liquid or medium. The lateral or cross passage 24 is incommunication with an outlet passage formed in the wall of the shell orcasing l, and having, at its upper end, a month .26 opening into thechamber 2 of the shell or casing; and the lowermost point of the mouth2b is in line, or approximately so, with the center longitudinally ofthe chamber, and is located in such relation to the rise of the water,or other liquid or medium in the chamber, that any oil, or lightsediment or material, on top of the water, or other liquid or mediumwill first flouv into the outlet passage, and this prior to the time thefloat is elevated, so as to open the discharge passage leading into thedischarge chamber 16, thereby removing oil, sediment and light materialfloating on the surface of the water, or other liquid or medium prior tothe flow of a free discharge of the water,

or liquid, or medium from the chamber :2,

thus maintaining the chamber 2 clear of oil and any floating sedin'ient,or material which would be liable to accumulate in thechamher andinterfere with the perfect operation of the float.

The float 27, in the form shown, is made in two halves or sections ofthin material, joined at the center by overlapping beads so as to bepractically air tight. Zach end of the float has an outwardly turned rim28 encircling a hole or opening 21); and the opening :29, for the upperend of the float, has secured therein a plug or reinforcement 30, andthe lower end of the float, in the opening 29, has secured therein aplug or reinforcement 31, depending from which is a tube 32 having apassage 33 and furnishing a guide or the lower end of the float and adisehar' e for air from the interior of the float. The tube 32 has, onits lower end, a seating face it which co-actswith the seat 33 aroundthe port 11' and closes the discharge pa'ssagc into the chamber it) whenthe float is down or in normal position, as shown in the ligurc; andwith the rising of the float the stem 3:! is also raised, opening theport 17 and allowing the oil,lloatage and water in the chamber .2 andpassage '25 to discharge into the chamber 16 for removal through thedischarge or vacuum p pe, as usual.

The rein forccment or plug 30, at the up er end of the float, has acentral hole 35, into which is entered a fixed pin 36 of a less diameterthan the hole 35, so as to leave a free passage around the pin foradmitting air from the chamber 2 into the interim of the float, as thewater of condensation, or liquid or medimn, rises in the float chamber.The guide pin 36 depends from the plug 12,

and the plug 19, on the under side of the screw threaded portion 1thereof, has a seating face 37, which, when the float is completelyraised, close. the opening or passage and prevents air from flowing intothe interior of the float from the float chamber. and at the same timethe discharge passage in the plug 18 is open for escaping water ofcondensation, or other liquid or me dium in the passage :25, until theamount of escape is suflicicnt to allow the floatto fall or return toits normal position, as shown in tho figure.

The wall 1, in the arrangement shown, has. at its lower end, an abutment38, which enters into the chamber 3, forming a U shaped passage with aleg 39, and a leg 40; and the leg -10 opens into the float chamber-2 ata pointbelow the lower end of the float, when in normal position, asshown in the figure. The leg 39 of the U shaped passage has entered intoits re eiving end a cage -11 ll:l\'lll lateral arms 42, with openingsbetween the arms, which cage supports a ball valve 42), held in place bythe arms or legs 42; and the ball valve 4.) co-acts with a valve seat llformed on the end of the union nipple .3 around the end of the passage(3 in said nipple. It will be understood that when the vacuum isoperating correctly the ball valve will be forced away from the seat 44,so as to furnish open communication into the inlet passage 3 for thewater of condensation, or other liquid or medium, to flow into the lowerend of the float chamber and rise in such chandler; but in the event ofback pressure. or failure of the vacuum to of water of condensation intothe chamber 2 of the float.

The wall of the chamber 16, on one side, has a by-pass to, with aseating face with which a seating end 46 coacts; and the seating cud 46is on a stem 47, having a screw threaded portion 45 entered into thewall of the chamber 16, so that by advancing and receding the stem 47,through the screw threaded portion lb, the end 46 can be seated to closethe by-pass 45, or unseated to open the bypass -l5 and allow the waterof condensation to flow from the passage 3 directly into the dischargechamber .16 without entering the float chamber. The stem 4-7, as shown,has a squared end 49 for receiving a turnkey, or other instrument, foroperating the stem; and the end 49 is surrounded by a wall it) outwardlyc.&t '-lnlil1g from a flange 31 on a closing plug 512, which plug isentered into a rim or wall 5;) at the lower end of the main shell orcasing; and, as shown, a packing 54 is located in advance of the plug 52to be compressed by the plug and furnish a tight joint around the stem.

The tiperation briefly is as follows: The water of enndensatitm, orother liquid ur medium. entering the pasmtge 3 from the radiator. 0rother snurt-e of supply. flows upwardly tltl'OttLTll the leg 40 into thebottom of the tloat ehamher and gradually rises in the chamber, and whenthe upper surface of the water 01' cnntlensatinn.
